Thanks Andy but I got the answer. I was using a Shared Recognizer. Now I'm using an InProc (non-shared) recognizer. Here is the code for those who are interested. It works fine, the InProc recognizer is the only recognizer that gets reco events in Win 7 and Vista:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim WithEvents RecoContext As SpInProcRecoContext
Dim InProcRecoContextRecognizer As SpInprocRecognizer

Private Sub MyTestProc()

        Dim MyFirstToken As New SpeechLib.SpObjectToken
        Dim MySecondToken As New SpObjectToken
        RecoContext = New SpInProcRecoContext
        InProcRecoContextRecognizer = RecoContext.Recognizer

Dim I As SpeechLib.SpInprocRecognizer
I = New SpInprocRecognizer

Dim myCategoryID As String = ""
Dim MyCategory As New SpObjectTokenCategory

        MyFirstToken = InProcRecoContextRecognizer.GetAudioInputs().Item(0)
        myCategoryID = MyFirstToken.Category.Id
        MyCategory.SetId(myCategoryID)

MySecondToken.SetId(MyCategory.Default())
InProcRecoContextRecognizer.AudioInput = MySecondToken

End Sub

Blazio,

The reason why your program may have worked on XP and not Windows 7 is, XP is SAPI4 compliant (the older Microsoft speech API SAPI 4).

Whereas, Windows Vista & 7 are SAPI 5 compliant (the newer Microsoftspeech API). So your program will not work with thelatter because of this reason.

Your best bet is to Google "SAPI 5" for Windows 7. There have been several versions of SAPI 5since it came out. The link below from Wikishows the different versions.

All,

I have a program that I originally built on XP. It works perfectly there. It presents passages of text to the user to read aloud, it provides excellent feedback, it's very accurate well behaved and reliable. What can I say, I'm a sucker for SAPI, I think it's one of the more amazing things I've encountered in my life.

Anyway, I finally ported it to Windows 7. And now things have pretty much gone haywire. I haven't been able to find good information on how to control what goes on there.

On xp, when I enable a reco_context, that's what's listening and that's what reacts. I'd like to achieve the same behavior on Windows 7, but I can't and I've spent days and days trying to figure it out. I see the small Speech Recognition window come up but I don't know what to do with it. I can see it correctly displaying the words that were spoken but they don't seem to go through to my enabled reco context. Sometimes they do, sometimes they don't.

To make it even worse, Win7 speech recognition seems to interpret some pronounced words as commands to the computer. Thus it clicks buttons, clicks tabs on the tabbed interface, everything jumps all around. It's not usable.

Can someone point me in the right direction. I assume I can control all of these behaviors programatically and get to where I need to be, but I don't know where the documentation for any of that would be.

Thanks for any help you can give
